Answer
Yes, Athanasius is considered one of the four great Eastern Doctors of the Church in the Catholic Church. The other three Doctors are Basil the Great, Gregory of Nazianzus, and Gregory of Nyssa. These four men were instrumental in shaping the early Church and their writings continue to be influential today. Athanasius was a theologian, bishop, and a key figure in the early Church's struggle against Arianism.
